Inductive lighting carpet / Carpet

People often go to the bathroom at midnight. It’s difficult to find the light switch and put on slippers in darkness. After turning on the lamp, people also feel uncomfortable because eyes can’t adapt to the strong light immediately.
So we designed this carpet. When people step on the carpet, a soft light will appear around feet. The room will be brighter if people walk more steps because every footprint left on the carpet is a light source. So people don't need to find the light switch. The light will continue 3 minutes. The light will gradually brighten while it will extinguish slowly. So our eyes can gradually adapt to the light.
